之前在简书上记录了一些笔记,现在将这些东西统一集中写在这里。

One》百度地图定位失效,定位到非洲

搞了一下午,各种权限,打断点都一直显示空白,放大定位后定位到非洲,表示getlocation中location的坐标都是(0,0),定位在非洲西海岸。最后解决问题:特么的居然是手机__没有授权,禁止了获取地理位置的权限!!!!!!!!!!!!!!

Two》Gradle 编译

finished with non-zero exit value2
这个主要是因为在我的工程目录中存在两个Jpush的so文件和JAR包。只要删除一个,重新build即可。

Three》Android Studio获取数字签名信息(SHA1)

Android Studio获取数字签名信息相对eclipse复杂些,搞了好长时间居然是Terminal指令输入时少输入了\debug.keystore。

以下是设置的具体步骤:
1.打开Android Studio下面的Terminal
2.定位到代码目录(一般自动定位)
3.输入“keytool.exe路径”-list -v -keystore “debug.keystore路径”

"C:\Program Files\Java\jre1.8.0_60\bin\keytool.exe" -list -v -keystore "C:\Users\Administrator\.android\debug.keystore"

\keytool.exe\debug.keystore一定要写
4.密钥库口令:android
5.得到数据签名信息

### Note Application or Functionality in IT Context In the IT context, a note application refers to software designed for creating, organizing, and managing textual information such as notes, lists, reminders, etc. These applications often provide features like real-time synchronization across devices, tagging, categorization, searchability, and sometimes integration with other productivity tools. The concept of sharing working objects between application components at runtime can be directly related to how modern note-taking apps function[^1]. For instance, these applications may use shared memory spaces or inter-process communication mechanisms to ensure seamless interaction among different parts of an app while maintaining performance efficiency. Additionally, when debugging complex systems involving graphical user interfaces (GUIs), libraries similar to Inspector—a Qt-based tool—can play crucial roles by allowing interactive inspection into lower levels of data models used within those GUI frameworks[^2]. Such capabilities are essential during development phases where understanding internal states becomes necessary for resolving issues effectively. Regarding Android-specific implementations mentioned through LayoutInflater example provided earlier[^3], it demonstrates one way contexts might influence layout inflations which indirectly affects UI elements rendering including potential custom views representing individual 'notes'. Here's simplified code snippet showing basic usage pattern: ```java // Example demonstrating typical utilization scenario. public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Obtain reference via system service method call. LayoutInflater inflater = LayoutInflater.from(this); View view = inflater.inflate(R.layout.activity_main, null); setContentView(view); } } ``` This piece illustrates obtaining `LayoutInflater` object using its factory method tied closely to current activity lifecycle state represented here symbolically under term **context**, thus affecting overall behavior dynamically based upon varying conditions present throughout execution period.
